Held between the two halves of that bracket is a steel collar which holds a bronze split bearing p/n 702058-6. (part 31 in the picture shown on the forum site) When the torque tube twists under loads exerted to the nose leg attached to the torque tube yoke, the tube yoke section rotates within that bronze bearing. Although the steel collar is held tight within the two halves of the centre brackets, if the friction between the bearing and yoke become too tight, there is nothing to stop that collar trying to rotate within the bracket which may also cause squeaking. Why the parts book call out that p/n for the bearing I dont know because it is not a replaceable/servicebale item. The only way to replace it is to remove the torque tube from the plane and debond/unbolt the end caps of the tube. I assume by lubricating you may mean spraying so may be that has penetrated within and between the bearing and tube and helped some what. For pictures of a broken down split bearing follow the Read this topic online here link below.

I don't think broken bonds are the problem though. I think it was just the bronze split bearing referenced by Ian. When I lubricated that area with some light silicone lubricant, the squeaking went away. I think some moisture had entered the area through a torn nose gear boot...I flew the plane about six hours then it sat outside overnight in a rain shower immediately before the squeaking started. The annual is about a month away, so we'll be replacing the boot, and maybe adding some lubricant to that bearing, although I'm not sure what the proper lubricant would be. I'd say we're really just trying to prevent corrosion there more than lubricating. Would something like LPS-3 be good for this? Thanks again for the help everyone...this is a great list! http://www.wotelectronics.com/flying/DSC04958%20-%20right%20outboard.JPG http://www.wotelectronics.com/flying/DSC04961%20-%20right%20inboard.JPG http://www.wotelectronics.com/flying/DSC04965%20-%20left%20outboard.JPG http://www.wotelectronics.com/flying/DSC04972%20-%20left%20inboard.JPG Read this topic online here: http://forums.matronics.com/viewtopic.php?p=240091#240091 ________________________________ Message 6 _____________________________________ Time: 10:49:49 AM PST US From: Gil Alexander Subject: Re: TeamGrumman-List: SL-60 for sale I guess it sold quickly and went to a good home in Las Cruces...:^) I edited the posting to mark it as sold. gil A >Gary, posted here... > >http://www.vansairforce.com/community/showthread.php?p=319199#post319199 > >Let me know when it sells and I will mark it appropriately > >gil A > >> >>Sure, thanks.

That's awesome. 0D ________________________________ Message 8 _____________________________________ Time: 10:28:29 PM PST US Subject: TeamGrumman-List: S-Tec From: teamgrumman@AOL.COM I'd like to meet the genius who designed, or, better yet, approved the design of the roll servo mount. Or Both. Genius. Sheer Genius. Forward Mount: The factory mounting holes are 3.6 inches apart. S-Tec chose 3.5 inch spacing. So, the installer is either crowds out both holes, drills both holes to 1/4 inch, or picks one and drills the other to fit. Aft Mount: The factory mount has 4 holes. The S-Tec mount has 4 holes. However, if you pick one, none of the other holes are in the right place. If the installer picks the two most obvious holes and crowds them out to fit, THEN, drills two new holes for the other two, the two mounts are 1/10 of an inch too close together. If the other two holes are picked, the mount is 3/8 inches to close together. Truth is, the original mount 'could' be modified to use. S-Tec didn't need redesign the whole mount. Bottom line is, there is no way to make the installation clean. ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message teamgrumman-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/TeamGrumman-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/teamgrumman-list Browse Digests http://www.matronics.com/digest/teamgrumman-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
